Angry No Sounds From Speakers !

I have a problem and maybe you can help me to give me any idea.

I had a minor accident with my BMW F32 and the headunit (NBT EVO) was out of the repair time.

I put the headunit back and now there is no sound from the speakers.

Any Idea ?

The fibre optic cable input line is flashing in red at the HARMAN KARDON AMPLIFIER (so the HEADUNIT sending signals to AMP.) but the output line is not flashing, lighting.

The headunit is play the music, i can change to CD or FM/AM mode, but the sound not working.

Sorry for my poor english

Thank you
